Copying one code from a Raspberry Pi to another. Trying to set up a second hydroponics system.

#!/usr/bin/env python

import RPi.GPIO
import time
import sys

# The Raspberry Pi pins used to control the power strips
setPin = 3

RPi.GPIO.setmode(RPi.GPIO.BCM)


runTime = int(sys.argv[1])

timeUnit = 'sec'

try:
    timeUnit = sys.argv[2]
    if timeUnit == 'min':
        runTime *= 60
except:
    print("")
    print('Defaulting time units to "sec" (other option: "min")')
    print('> ' + sys.argv[0] + ' sec')
    print("")

    
#Set up the pin as an output    
RPi.GPIO.setup(setPin, RPi.GPIO.OUT)


print('')
startTime = time.strftime('%a, %d %b %y: %H:%M:%S', time.localtime())
print("Start pump at:", startTime)

#Turn pin on
RPi.GPIO.output(setPin, True)
print('on')

for i in range(runTime):
    time.sleep(1)
    if i%10 == 0:
        print( '{t}/{n} sec. ({p:.1f}%)'.format(t=i, n=runTime, p=100.0*i/runTime) )

#Turn pin off
RPi.GPIO.output(setPin, False)
print('off')
endTime = time.strftime('%a, %d %b %y: %H:%M:%S', time.localtime())
print("End pumping at:", endTime)

This is Blas’s icosahedra and tetrahedra set that was made as a math project. Then he made it for a present. Later on the Makerspace Business Club started selling them. A tetrahedron has four sides each side has a triangle face. With that in mind Blas decided to add puzzle edges to the sides of the triangles. Inside the big tetrahedra there are a bunch of triangle sides that are used for having fun and creating cool things. It is possible to make an icosahedra with the little triangles. Each edge of the small triangles have either one or two tabs for attaching one to another. Which means there are four different types of puzzle piece. They are fun to play with.

Over the past two days I have been designing and lasering my organizer box. When I first tried to put it together the shelves that I added did not align with the cutout places it was supposed to fit in. So, I redesigned the shelves hoping it would work. But, when I printed it again it did not fit. I ended up sawing off the edges of the shelf where it was supposed to fit in—to make it only insert on one side of the box. I glued the other sides to make sure it wouldn’t fall. Hopefully this will work.

Sarah and I finished making our global rings. We used a photo editing software to make the perfect size for our pictures. We printed them out on cardstock paper with an inkjet printer. Then we glued the pictures in our rings using superglue and put a protective layer of epoxy over them.

Zoe and I completed our rings. We used a photo editing software to size our pictures. Once we printed them out on card stock paper with an inkjet printer. We glued them to the rings using super glue and put a clear epoxy protective coat.

I had a few problems with this. At first, when I was trying to design it the first time, it wouldn’t come out correct. The words would be mashed together and the actual languages would be added with different things. I had to re-save it about three times before it actually came out correctly. I had to save it as a PDF file, had to convert text to curves, and then I had to transfer the file to the laser cutter.
